Shape dependent finite-size effect of critical two-dimensional Ising model on a triangular lattice
Xintian Wu, Nickolay Izmailian, Wenan Guo
Using the bond-propagation algorithm, we study the finite-size behavior of the critical two-dimensional Ising model on a finite triangular lattice with free boundaries in five shap…
Finite size behaviors of critical Ising model on a rectangle with free boundaries
Xintian Wu, Nickolay Izmailian, Wenan Guo
Using the bond-propagation algorithm, we study the Ising model on a rectangle of size with free boundaries. For five aspect ratios , the critical fre…
Coefficient of performance at maximum figure of merit and its bounds for low-dissipation Carnot-like refrigerators
Yang Wang, Mingxing Li, Z. C. Tu +2
The figure of merit for refrigerators performing finite-time Carnot-like cycles between two reservoirs at temperature and () is optimized. It is found that the co…
Critical manifold of the Potts model: Exact results and homogeneity approximation
F. Y. Wu, Wenan Guo
The -state Potts model has stood at the frontier of research in statistical mechanics for many years. In the absence of a closed-form solution, much of the past efforts have foc…
